Purpose: Correcting lower limb angular deformities in the skeletally immature patient with guided growth is a very common procedure. Using an 8-plate construct to produce reversible hemiepiphysiodesis allows correction of the mechanical axis of the limb. It has become routine strategy to remove only the metaphyseal screw from the 8-plate construct after desired correction is achieved, in order to ease its reinsertion in case of deformity recurrence. In this study, we evaluated the efficacy and safety of this technique. Methods: We reviewed the results of 80 patients (133 limbs) who were treated by guided growth using 8-plate hemiephisiodesis around the knee. After achievement of the correction goal, both screws and plate were removed in 78 limbs while only the metaphyseal screw was removed in 55 limbs. Results: The mean age of patient was 8.9 years at the time of surgery. Within the group whose metaphyseal screw was removed, 12 limbs showed radiographic signs of deformity recurrence and underwent reinsertion of the metaphyseal screw. In 9 of the cases of metaphyseal screw reinsertion, the plate or its location had to be changed (mean follow-up after screw removal was 14 mo). There were 2 cases where leaving the plate with an epiphyseal screw caused a radiographic bone bar and undesired clinical growth arrest. Conclusions: On the basis of our experience, leaving the 8-plate construct with an epiphyseal screw in place exposes the patient to risks of bony bar, growth arrest, and an additional surgery for hardware removal. The majority of 8-plate constructs are not suitable for reinsertion of the metaphyseal screw.
Sclerosing osteomyelitis of Garré continues to be a puzzling entity, with a nonspecific clinical description and course, an obscure pathogenesis, and no consensus on a predictable and helpful method of treatment. The proposed treatment options according to the literature are observation, analgesics and NSAIDs, and bone curettage. Here we present a 15-year-old girl treated by resection of a 12 cm-long lesion after failed conservative treatment, followed by bone transport using a circular external fixator. This treatment method has not been described previously for this condition. The duration of bone transport was 3 months, and the total duration of the frame treatment was 12 months. After hardware removal, and at 2.5-year follow-up, the patient was asymptomatic and achieved good functional results. To the best of our knowledge, this is the first description of bone resection and transport for the treatment of this condition, even though it is well described for the treatment of chronic osteomyelitis and other conditions necessitating bone resection. On the basis of this case we suggest that resection and bone transport using a circular external fixator for the treatment of sclerosing osteomyelitis of Garré might be an effective and safe method. Of course, being a rare entity, large cohorts are difficult to obtain, and more data and longer follow-up are required to form a convincing recommendation. Level IV evidence.
Objective Smartphones have the ability to capture and send images, and their use has become common in the emergency setting for transmitting radiographic images with the intent to consult an off-site specialist. Our objective was to evaluate the reliability of smartphone-based instant messaging applications for the evaluation of various pediatric limb traumas, as compared with the standard method of viewing images of a workstation-based picture archiving and communication system (PACS). Methods X-ray images of 73 representative cases of pediatric limb trauma were captured and transmitted to 5 pediatric orthopedic surgeons by the Whatsapp instant messaging application on an iPhone 6 smartphone. Evaluators were asked to diagnose, classify, and determine the course of treatment for each case over their personal smartphones. Following a 4-week interval, revaluation was conducted using the PACS. Intraobserver agreement was calculated for overall agreement and per fracture site. Results The overall results indicate “near perfect agreement” between interpretations of the radiographs on smartphones compared with computer-based PACS, with κ of 0.84, 0.82, and 0.89 for diagnosis, classification, and treatment planning, respectively. Looking at the results per fracture site, we also found substantial to near perfect agreement. Conclusions Smartphone-based instant messaging applications are reliable for evaluation of a wide range of pediatric limb fractures. This method of obtaining an expert opinion from the off-site specialist is immediately accessible and inexpensive, making smartphones a powerful tool for doctors in the emergency department, primary care clinics, or remote medical centers, enabling timely and appropriate treatment for the injured child. This method is not a substitution for evaluation of the images in the standard method over computer-based PACS, which should be performed before final decision-making.
The mode of Scheuermann's disease inheritance and its phenotypic traits in probands and their relatives were studied in 90 pedigrees (90 probands and 385 relatives). The disorder was identified as a genetically related pathology inherited by autosomal dominant type, controlled by a mutant major gene, as a kyphotic deformity without signs of vertebral bodies' anomaly and torsion. Morphological and biochemical studies showed disturbance in the structure of vertebral growth plate anterior aspects at the level of deformity, defects in proliferation and differentiation of chondrocytes, and change in proteoglycan spectrum in cells and matrix. Twelve candidate genes were studied in chondrocytes isolated from vertebral growth plates of patients with Scheuermann's disease. The study results included disorder in the IHH gene expression and preservation of the expression of PAX1, two aggrecan isoforms, link protein, types I and II collagen, lumican, versican, growth hormone and growth factor receptor genes, and proliferation gene. Preservation of the SOX9 gene (transcription gene) probably indicates posttranscriptional genetic disorders. The study is under way.
Supramalleolar osteotomy (SMO) is useful for the correction of various deformities around the ankle joint,especially deformities of the distal tibia secondary to partial growth arrest, foot equinus, and hind foot deformities. By definition, this osteotomy cuts through the tibia and fibula approximately 2–3 cm above the ankle joint.It can be performed by various techniques, each of them have advantages and disadvantages. Gigli saw SMO can be performed percutaneously with minimal soft tissue dissection, leaving a very smooth bone surface, which is especially useful for the correction of rotational deformities. Over a period of 6 years we performed eight gigli saw SMO in seven male patients and one female patient with a mean age of 13.6 years. All patients had multiplanar deformities with some shortening (range 15–40 mm) and underwent correction and lengthening by Taylor spatial frame. Treatment goal was achieved in all patients with minimal complications. On the basis of our experience, we believe that gigli saw SMO can be performed safely. This osteotomy, in conjunction with the Taylor spatial frame, became our treatment of choice for the correction of ankle and hindfoot deformities.The evidence is level 4, case series.
